医用三通管在人工气道持续吸氧及气道湿化中的应用效果观察

目的 探讨医用三通管在人工气道持续吸氧及气道湿化中的应用效果.方法 将ICU建立人工气道后脱机且需持续吸氧的患者50例,随机分为实验组和对照组,每组各25例,实验组患者采用医用三通将氧气、湿化液合二为一输入气道内进行给氧与湿化；对照组采用传统方法双管置入方法,即将吸氧管和湿化管分别接上去掉针头的一次性头皮针管后同时插入人工气道内.比较两组患者气道湿化效果、并发症发生率及平均住院时间.结果 实验组患者气道湿化效果明显优于对照组,呼吸道并发症发生率明显低于对照组,平均住院时间明显短于对照组,两组比较,均P＜0.05,差异具有统计学意义.结论 在人工气道后持续吸氧及气道湿化的患者中,使用医用三通管将氧气、湿化液合二为一输入气道内,提高湿化效果,减小气道阻力及并发症的发生,从而降低患者平均住院日.

Effect of medical three-way pipe on continuous oxygen supplying and airway humidification after establishing the artificial airway

Objective To discuss the effect of medical three-way pipe on the continuous oxygen supplying and airway humidification after establishing the artificial airway. Methods 50 ICU patients undergoing continuous oxygen supplying after establishing the artificial airway were evenly divided into the experiment group and the control group randomly. In the experiment group the medical three-way pipes were used to mix both oxygen and moist liquid together in the airway for humidification, while in the control group traditional double tube method was used for humidification. The airway humidification effects were compared between the two groups including the incidence of complications and average hospital days. Result Compared with the control group, the experiment group had superior performance in airway humidification, with less respiratory tract complications and fewer hospital days (P < 0.05). Conclusion Medical three-way pipes which mix oxygen and moist liquids together in the airway can not only enhance the humidification effect and reduce the resistance of the respiratory tract and risk of complications, but also shorten the hospitalization durations.
